In 2018, the International Waterlily and Water Gardening Society (IWGS) held its third New Waterlily Competition at Longwood Gardens in Kennett Square, Pennsylvania. This year, 16 entries were submitted from around the world by waterlily hybridizers across the three categories: hardy, intersubgeneric (ISG) and tropical. The entries were grown under the supervision of senior gardener Tim Jennings at Longwood Gardens. The 2018 judging panel was composed of 19 judges from different countries whose expertise ranged from nursery and botanical garden waterlily growers to waterlily hybridizers and enthusiasts.

We would like to thank Tim Jennings and Longwood Gardens for their support in hosting the IWGS New Waterlily Competition on-site for the past three years, Jolisa Copeman (an intern at Longwood Gardens) for her incredible photography of the competition’s waterlilies, and last but not least, the judges who volunteered their valuable time and knowledge to this competition. Looking ahead, 2019 will see the IWGS New Waterlily Competition relocate to a new location — sunny South Florida. The competition’s waterlilies will be grown under the supervision of Danny Cox, the Aquatic Areas Specialist at Naples Botanical Gardens.
